Summary: Soil erosion and deposition have effects on soil microbial communities, which can be regulated by organic carbon levels. The study found that erosion reduced bacterial diversity while deposition increased it. Both erosion and deposition caused a decrease in fungal diversity. Increasing organic carbon levels enhanced the network complexity of bacteria and fungi at eroded and depositional sites.

Summary: This study examined the impact of soil microbial community and oxygen availability on moisture content, soil pH, and bacterial composition during the decomposition of poultry carcasses. The research found that bacterial taxa composition varied between different burial set-ups and across time points, with differences in the dominant phyla and genera at different stages of decomposition. The presence of intact microbial communities and oxygen significantly affected the changes in moisture content, pH, and bacterial composition throughout the decomposition process.

Summary: The microbial abundance, diversity, and interactions in soil play a crucial role in ecosystem functions. Viruses can regulate microbial communities and processes, but the understanding of their relationships with environmental conditions is lacking. Soil properties like organic matter and nitrate content influence viral and bacterial abundance and reproduction strategies. Land management and physicochemical properties shape bacterial community composition, while viral community composition is closely related to cover plants. This study sheds light on how environmental factors influence virus-host interactions in soil ecosystems.

Summary: Investigating microbial communities is beneficial for evaluating the effectiveness of wastewater treatment devices. A novel five-section anoxic/aerobic device was proposed and proved feasible in bio-ecosystems, with distinct microbial communities formed in different sections. The device's diverse microbial community efficiently removes pollutants, making it suitable for rural areas with low-strength wastewater.

Summary: Sludge treatment reed beds (STRBs) are an economically feasible and eco-friendly approach to sewage sludge management, relying on complex interactions between plants and microorganisms. This study explored the diversity and spatial distribution of bacteria in different STRBs, with the MCF bed demonstrating the best performance and biodiversity. Results showed that Bacteroidetes, Proteobacteria, and Firmicutes were the dominant phyla, and Nitrospira played a key role in nitrogen metabolism in the STRBs.

Summary: In this study, a direct PCR method was evaluated as a cost-effective and time-saving alternative to traditional DNA extraction methods for analyzing microbial communities. The direct PCR method showed comparable efficiency to the conventional DNeasy PowerSoil protocol, with higher efficiency for extracting gDNA from Gram-negative strains. This method is significantly less expensive and faster, making it a potential solution for high-throughput large-scale bacterial community analysis.

Summary: This study examined the effects of Cry1B protein on the growth and development of non-target natural enemies. The results showed that Cry1B protein had no significant impact on the health indicators of P. astrigera, but it did reduce the number of symbiotic bacteria species and species diversity. The effects of Cry1B protein on symbiotic bacteria varied by growth and development stage and sex.

Summary: This study investigated the effects of AMF on the structure and composition of bacterial communities in the rhizosphere of plants under different chromium concentrations. The results showed that AMF inoculation decreased the Cr(VI) concentration in the rhizosphere soil and promoted nutrient uptake by plants. Furthermore, AMF increased bacterial diversity and abundance in the rhizosphere soil. These findings suggest that AMF can enhance the tolerance of wetland plants to soil Cr pollution by improving the structure and composition of rhizosphere bacterial communities.

Summary: This study investigated the changes in soil bacterial communities following secondary succession of old-field on the Loess Plateau of China. The results showed that the abundance of soil bacteria increased while richness and diversity decreased after old-field succession. The composition of the bacterial community also shifted, with a decrease in oligotrophic groups and an increase in copiotrophic Proteobacteria. These changes in bacterial communities have implications for the decomposition and accumulation of soil organic carbon and nitrogen.

Summary: In this study, the effects of long-term bioreactor (un)stability on resistance to shock loads were evaluated. The results showed that the reactor with stable operation performed better in terms of resistance to a sudden increase in organic loading rate, despite having lower microbial community diversity. The operation history of a reactor plays a crucial role in determining its ability to withstand environmental perturbations.

Summary: The gut microbiota structures were investigated and compared in complete intensive feeding pattern (CP) and extensive feeding pattern (EP) groups using 16S rRNA gene sequencing. Results showed that the abundance of core microbial flora in the CP group was significantly higher than in the EP group, with CP group also showing greater community diversity. Functional prediction analysis suggested that the CP group may have faster growth and increased fat accumulation capacity, but weaker disease resistance compared to the EP group.

Summary: This study investigated the effects of Bacillus coagulans (BC) and Lactobacillus plantarum (LP) on the fermentation characteristics, microbial community, and aerobic stability of ensiled triticale. The results showed that the addition of BC and LP can lower the pH, water-soluble carbohydrates, neutral detergent fiber, and ammonia nitrogen content of ensiled triticale, and increase the lactic acid concentration, lactic acid/acetic acid ratio, and aerobic stability. Furthermore, the application of BC and LP can also alter the composition of bacterial communities. Therefore, the combination of BC and LP is crucial for improving the fermentation quality and aerobic stability of ensiled triticale.

Summary: A growing population and limited water resources have created a deficit in water sources for agriculture. To address this, some countries are using recycled treated water for irrigation. However, the continuous operation and direct connection of recycling systems to irrigation reservoirs pose risks of irrigation system malfunctions and potential contamination of pathogens. Therefore, the development of early warning systems for biological water contamination is crucial.

Summary: Early life exposure to environmental microbes in chickens has long-lasting impacts on gastrointestinal microbiome development and host health and growth. This study demonstrates that fecal microbiome transplant (FMT) from adults to day-of-hatch chicks leads to increased body mass and improved feed efficiency in 6-week-old birds. The study also reveals that FMT has a significant and long-lasting effect on the microbial community composition and function of the ceca.
